Decreasing Unnecessary Antibiotic Usage in Patients Admitted With Bronchiolitis.

BACKGROUND AND OBJECTIVES: Bronchiolitis is a viral syndrome that occurs in children aged <2 years and is a common reason for admission to children's hospitals. The American Academy of Pediatrics bronchiolitis guideline discourages routine antibiotic therapy for bronchiolitis. Despite this, there is high use of antibiotics in this patient population. METHODS: We performed a retrospective chart review of all patients aged ≤2 years admitted to our tertiary care center with bronchiolitis during 2 subsequent respiratory seasons. Between the 2 seasons, we provided an intervention to our hospital medicine group, which included a didactic review of American Academy of Pediatrics bronchiolitis guideline followed by subsequent, ongoing reinforcement from antibiotic stewardship weekday rounds. RESULTS: We were able to achieve a 40% decrease in overall antibiotic use between the 2 study periods (25% vs 15%, P < .001). CONCLUSIONS: Provider education, along with focused antibiotic stewardship audits with real-time feedback, resulted in decreased use of antibiotics in patients admitted with bronchiolitis.

Travel distance to screening facilities and completion of abnormal mammographic follow-up among disadvantaged women.

PURPOSE: Although many studies have examined factors in predicting incomplete and delay in abnormal mammogram follow-up, few have used geospatial methods to examine these factors. Consequently, the purpose of this study was to examine the relationship between travel distance to health facilities and completion of abnormal mammogram follow-up among disadvantaged women in South Carolina. METHODS: Women participating in South Carolina's Best Chance Network between 1996 and 2009 with abnormal mammogram were included in the study. Kaplan-Meier survival was used to describe the probability of work-up completion after abnormal mammogram among different distance categories, and Cox proportional hazards model was used to further assess the relationship between work-up completion and travel distance to the screening provider and mammography facility. RESULTS: Among 1,073 women, there was significant difference in time to completion of abnormal mammogram work-up by race; African American women had longer time to completion compared to European American women. Accounting for race, age, previous mammograms, income, and insurance status, women who lived closest to their diagnosing mammography facility were more likely to complete their work-up compared to those who lived the farthest (HR = 1.41; 95% CI = 1.00-1.80). CONCLUSIONS: Distance to the diagnosing mammography facility may play a role on the completion of abnormal mammogram work-up.

Planting Healthy Roots: Using Documentary Film to Evaluate and Disseminate Community-Based Participatory Research.

Documentary filmmaking approaches incorporating community engagement and awareness raising strategies may be a promising approach to evaluate community-based participatory research. The study purpose was 2-fold: (1) to evaluate a documentary film featuring the formation and implementation of a farmers' market and (2) to assess whether the film affected awareness regarding food access issues in a food-desert community with high rates of obesity. The coalition model of filmmaking, a model consistent with a community-based participatory research (CBPR) approach, and personal stories, community profiles, and expert interviews were used to develop a documentary film (Planting Healthy Roots). The evaluation demonstrated high levels of approval and satisfaction with the film and CBPR essence of the film. The documentary film aligned with a CBPR approach to document, evaluate, and disseminate research processes and outcomes.

Decreased Cancer Mortality-to-Incidence Ratios with Increased Accessibility of Federally Qualified Health Centers.

Federally qualified health centers (FQHCs) offer primary and preventive healthcare, including cancer screening, for the nation's most vulnerable population. The purpose of this study was to explore the relationship between access to FQHCs and cancer mortality-to-incidence ratios (MIRs). One-way analysis of variance was conducted to compare the mean MIRs for breast, cervical, prostate, and colorectal cancers for each U.S. county for 2006-2010 by access to FQHCs (direct access, in-county FQHC; indirect access, adjacent-county FQHC; no access, no FQHC either in the county or in adjacent counties). ArcMap 10.1 software was used to map cancer MIRs and FQHC access levels. The mean MIRs for breast, cervical, and prostate cancer differed significantly across FQHC access levels (p < 0.05). In urban and healthcare professional shortage areas, mean MIRs decreased as FQHC access increased. A trend of lower breast and prostate cancer MIRs in direct access to FQHCs was found for all racial groups, but this trend was significant for whites only. States with a large proportion of rural and medically underserved areas had high mean MIRs, with correspondingly more direct FQHC access. Expanding FQHCs to more underserved areas and concentrations of disparity populations may have an important role in reducing cancer morbidity and mortality, as well as racial-ethnic disparities, in the United States.

Racial disparities in breast cancer mortality in a multiethnic cohort in the Southeast.

BACKGROUND: Although much has been done to examine those factors associated with higher mortality among African American women, there is a paucity of literature that examines disparities among rural African Americans in South Carolina. The purpose of this investigation was to examine the association of race and mortality among breast cancer patients in a large cohort residing in South Carolina for which treatment regimens are standardized for all patients. METHODS: Subjects included 1209 women diagnosed with breast cancer between 2000 and 2002 at a large, local hospital containing a comprehensive breast center. Kaplan-Meier survival curves were calculated to determine survival rates among African American and European American women, stratified by disease stage or other prognostic characteristics. Adjusting for various characteristics, Cox multivariate survival models were used to estimate the hazard ratio (HR). RESULTS: The 5-year overall all-cause mortality survival proportion was ∼78% for African American women and ∼89% for European American women, P < 0.01. In analyses of subpopulations of women with identical disease characteristics, African American women had significantly higher mortality than European American women for the same type of breast cancer disease. In multivariate models, African American women had significantly higher mortality than European American women for both breast cancer-specific death (HR, 2.41; 95% confidence interval [CI], 1.21-4.79) and all-cause mortality (HR, 1.42; 95% CI, 1.06-1.89). CONCLUSIONS: African American women residing in rural South Carolina had lower survival for breast cancer even after adjustment for disease-related prognostic characteristics. These findings support health interventions among African American breast cancer patients aimed at tertiary prevention strategies or further down-staging of disease at diagnosis.

Reducing cancer disparities through innovative partnerships: a collaboration of the South Carolina Cancer Prevention and Control Research Network and Federally Qualified Health Centers.

The South Carolina Cancer Prevention and Control Research Network, in partnership with the South Carolina Primary Health Care Association, and Federally Qualified Health Centers (FQHCs), aims to promote evidence-based cancer interventions in community-based primary care settings. Partnership activities include (1) examining FQHCs' readiness and capacity for conducting research, (2) developing a cancer-focused data sharing network, and (3) integrating a farmers' market within an FQHC. These activities identify unique opportunities for public health and primary care collaborations.

Prevalence of hepatitis B virus (HBV) infection among Hmong immigrants in the San Joaquin Valley.

Chronic hepatitis B infection (HBV) is the major cause of primary liver cancer worldwide and Asians are disproportionately affected. The prevalence of HBV among most Asian American groups has been well documented, except in Hmong immigrants in the United States. The aim of this study was to determine the prevalence of HBV among Hmong immigrants in the San Joaquin Valley of California. A convenient sample of 534 Hmong age ≥18 years was recruited at various locations throughout Fresno County. Blood samples from study participants were collected and tested for hepatitis B surface antigen (HBsAg) by enzyme-immunoassay. Two hundred and eighty-nine females and 245 males of Hmong descent (mean age, 43.93) were screened. Eighty-nine (41 males and 48 females) were positive for HBsAg, which accounts for a prevalence of 16.7% (95% C.I. 13.5-19.9). The majorities of HBsAg positive patients were ≥40 years (64.2%), married (66.7%), born in Laos (87.3%), and had lived in the United States ≥20 years (62.5%). Only 37.5% of the participants reported having a primary care physician. Our study revealed that approximately one out of every six Hmong immigrants screened was infected with HBV. Based on our findings, more than one-third of these infected patients have no primary care physician to provide further treatment, surveillance for liver cancer, or vaccination of their families. This supports the Institute of Medicine's recent recommendations to the Center for Disease Control to engage in a national Hepatitis B surveillance system.
